Whales in San Francisco Bay

Roughly 30 gray whales have been spotted in the Bay this season, many more than is typical. Sadly, there have also been at least 14 deaths this year, which is more than in all of 2024. 

We are investigating to help determine the cause of these deaths. By gaining insights into what is causing these tragedies, we can better understand how to help prevent them.

Historical Isolates of Dolphin Morbillivirus: Origin and New Data

  • Infectious disease
  • Pathology

Abstract

Dolphin morbillivirus (DMV) was isolated in striped dolphins Stenella coeruleoalba from the Mediterranean Sea stranded along the coast of Spain during a lethal epidemic that killed thousands of individuals in 1990-1992. Though some of these isolates (MUC, 16A and the reference strain) have been extensively characterised, details on their origin were not reported in the literature, and records for these isolates are often difficult to trace and are, sometimes, erroneous. Here, we provide unpublished biological and histopathological data for these isolates, summarize the literature on their characterization and make suggestions for future studies.
